The U.S. Army Air Corps (USAAC) Alaska Flight of 1934 departing Fairbanks Alaska on flight back to Washington, DC. Their YB-10 aircraft are seen in a line on the airfield. Spectators are at the edge of the field to see them off. Next, the aircraft are seen taxiing out for takeoff, with their Commander, Lieutenant Colonel Henry Arnold, piloting the lead aircraft, the "City of Fairbanks." Other aircraft follow in succession. Colonel Arnold's airplane takes off and proceeds in a shallow climb. Slate tells first leg is 640 miles to Juneau in 3 hours and 55 minutes. Map shows North America with outbound course to Alaska from Washington, DC, traversing the Great Lakes, Edmonton, Prince George, and White Horse, to Fairbanks. But a moving arrow shows return route via Juneau. Snow-covered mountains seen from a YB-10 on this return leg. Aerial shots of several YB-10s in formation. Slate announces next leg as 940 miles and 5 hours and 40 minutes to Seattle, Washington State. Aircraft and crews of the returning Alaska Flight, seen on a grass field in Seattle. Lieutenant Colonel Henry Arnold, expedition commander, leads his fliers across the field. Slate states remaining distance to Washington, DC, as 2700 miles and 14 hours. More shots of YB-10s in formation aloft. Shot of a YB-10 with farmland below. Ten YB-10s seen in formation, and the animated map completes the journey to Washington, DC. Aerial view from above of several YB-10s below, flying over the Potomac River, in Washington, DC, with the Lincoln Memorial, and Arlington Memorial bridge visible below. The formation of 10 planes barely visible above the Capitol building. The YB-10 named Juneau, taxiing across Bolling Field, after landing. (This segment of film is reversed, so the name and Alaska Flight logo are mirror-reversed.) The last of the 10 aircraft pulls into position on the flightline. Lieutenant Colonel Henry (Hap) Arnold stands in front of his fliers who hold a large totem pole souvenir. Secretary of War, George H. Dern, greets the returning aviators and poses next to Colonel Arnold.
